TROLLEY-WHEEL MOUNT.

LIAQATY.

Application filed June 1, 1914.

To all whom it may concern.

Be it known that I, JOHN JAMES, a citi- Zen of the United States ofAmerica, residing at Woodlawn, in the county of Beaver and State ofPennsylvania, have invented certain new and useful Improvements inTrolley-ld heel Mounts, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to trolleys, and has for its object to provide adevice of such class, with means in a manner as hereinafter set forthfor maintaining the trolley wheel in connection with the trolley wire,especially when rounding curves.

With the foregoing and other objects in view, the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which come within the scope of the claim hereuntoappended.

In the drawings, wherein like reference characters denote correspondingparts throughout the several views :Figure 1 is a side elevation of atrolley in accordance with this invention, and Fig. 2 is a frontelevation, partly in section.

Referring to the drawings in detail, the trolley comprises a pole 3, tothe upper end of which is secured by the holdfast devices 4:, a harp.The harp consists of a pair of angle-shaped sections including anupwardly extending arm 43, and a horizontally disposed arm 5. Each ofthe horizontally disposed arms 5 has its inner end terminating in asemi-cylindrical socket forming member 6. The members 6 oppose eachother to provide a socket 7 for the reception of the upper end of thepole 3, and through said socket forming member 6 and the upper end ofthe pole 3 extend the holdfast devices 4, whereby the harp is fixedlysecured to the pole 3.

Each of the upright arms 1 of the harp near its free end is providedwith an opening 8, and extending through said openings 8 is a shaft 9,provided on its ends with nuts 10, which abut against the outer face ofthe arms 46, and said shaft 9 is further provided Specification ofLetters Patent.

with nuts 11, which abut against the inner face of the arms P. The endsof the shaft 9 are threaded as at 12, for the reception of the nuts 10and 11, and these latter fixedly secure the shaft 9 to the harp.

Journaled upon the shaft 9, is a trolley wheel formed of two sections 13and 1a, which are so shaped as to provide a peripheral groove 15, thewall of which travels against the trolley wire 16, when the trolleywheel 13 revolves. The sections 13 and 1 1 of the trolley wheel areprovided with plates 17, and bearing against said plates 17 are coiledsprings 18, for maintaining the sections 13 and 1% of a trolley wheel inabutting engagement and said springs furthermore constitute means formaintaining the trolley wheel centrally of the shaft 9, and also allowof the trolley wheel shifting upon said shaft when occasion so requires,after being shif"- ed to restore the wheel to normal position which iscentrally of the shaft 9.

The springs 18 surround the shaft 9, and are interposed between theplate 17 and stop collars 19, which are mounted upon the shaft 9. Thenuts 11 arrest movement of the collars 19 in one direction.

lVhat I claim is A trolley wheel mount including a pole, a harp formedin sections and having a socket receiving one end of the pole therein,an axle removably mounted in the arms of said harp and having the endsthereof threaded, portions of said axle projecting beyond the arms ofthe harp, nuts engaged with the projecting ends of said axle to securethe latter in place, a trolley wheel formed in two sections looselymounted on said axle, coil springs encircling said axle, between thesections of said wheel and the arms of the harp, whereby to retain thetwo sections together in operative position and additional nuts on thethreaded portions of the axle interposed between the arms of the harpand the ends of the springs, whereby to adjust the tension of saidsprings in the securing of the sections of the wheel together.

In testimony whereof I atfix my signature in the presence of twowitnesses.
